Unfortunately, not everyone who goes to SXM is a member of TTOL. Facebook provides me an opportunity to stay in touch with dozens of folks across the country who I may see only once a year, if that. I find it an invaluable tool that allows me to stay in touch with people I don't see face to face very often. And I can post a photo from my phone to a FB group with pretty much one click. I have posted no personal information to my Facebook account and accept friend requests generally only from those I have met face to face; there are a few exceptions, but my general rule is to be "friends" only with those folks I've met in person. For me, it's a wonderful tool.
